GORKHILL, OF ROCHESTER, NEW YORK.
IMPROVEMENT IN GLOBE-VALVES.
Specification forming part of Letters Patent No. 209,382, dated October 29, 1878 application filed 4 December 27, 1876.
To all whom it may concern:
Be it known that I, HENRY R. GORKHILL, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Globe -Valves, which improvement is fully set forth in the following specification and accompanying drawing, in which Figure 1 is a central section of the globe, showing the contained valve, &c.; and Fig. 2 shows the globe or shell with the cap removed, looking in upon the valve 8.
The object of my invention is to improve a globe-valve, principally by casting a mass in the middle of the back chamber, reaching from the partition between the chambers across to the shell of the globe, and passing the valve-stem through the mass, for the purpose of keeping the stem from coming in contact with the contents of the chamber, thus preventing leaka 'c.
In the drawing, A is the shell or wall of a globe -valve, the interior space of which is divided into two chambers by the partition a, said chambers respectively opening; out at opposite ends of the globe. s is a valve, in the form of a circular disk, seated on thepartition a. with which it forms a steam-tight joint. The stem h of the valve passes out through the sleeve 13, and is provided at the end with a crank or lever, (J, by which it may be operated.
The valve 8 and seat or partition 0 are pro- .vided with similar openings 0, circular orof other suitable form, and of any desired number, which, when made to coincide, form passage-ways between the said chambers e and 0. Through the sand-core placed in the mold to form the chamber 0', when the globe-shell A is cast, I cause a cylindrical hole to be made, which, when the shell or mold is poured, simultaneously fills with metal, forming the mass or column 1', reaching trom the partition a centrally across the said chamber 6 to the outer wall of the shell. This mass or tie braces and stift'ens the partition or valve-seat a, and-When bored out forms a sleeve or sheath for the "alve-stem h, and renders a steamtight joint between the valve-stem and shell in the vicinity of h unnecessary.
Globe-valves having a separate piece fitted into one side of the shell, and reachinginward to the partition between the chambers and at right angles th ereto,h ave been h eretofore made.
These pieces are fitted to place at the expense of much labor and time; and to avoid this large amount of work I at once cast a mass or column, r, within the chamber 0, substantially as shown and above described.
The chamber 0 is covered and closed by the screw-cap D, which, when unscrewed, allows the valve to be taken out. The cap D has a hole bored into the center of its inner surface, in which a spiral spring, 0, isinserted, which, when the cap is screwed to its place, presses moderately upon the valve, holding it to its seat.
Globe -valves having the valvestem inclosed where it passes through the chamber of the globe have been before known and used. Such, broadly, I do not claim.
I claim as my invention 1. A globe-valve shell cast with a mass, 0", forming a sleeve or sheath for the valve-stem and uniting or tying the partition a between the chambers with the outside shell, said shell and mass 1 being solid and in one piece, substan tiall y as described, and for the purpose set forth.
2. A globe-valve consisting of a shell, A, having a tying-mass, r, forming a sleeve or sheath for the valve stem, cast within the chamber 6, and forming one piece with the shell, in combination with valve and seats and a and valve-stem h passing longitudinally through said mass r, all constructed and arranged substantially as shown and described.
